Lung Recruitment Maneuver as a Potential Predictor of Fluid Responsiveness in Mechanically Ventilated Pediatric Patients

In this research study we want to learn more about using non-invasive tools as a way to predict whether or not a child under general anesthesia will require and respond to fluid administration.

It is important for an anesthesiologist to know if a child would respond to fluid administration so that they can provide the optimal intervention for low blood pressure and avoid unnecessary treatment.
